Brocken Eco Advanced is 149mm high.

And very beefy Scythe Mugen 5 would be 154,5mm in standard version.
Though in stock RGB version is 3mm higher.

But with convex base optimized for dented heatspreader of Intels they would need grinding/lapping base flat for good wide area contact with convex heatspreader of Ryzens.
This was propably about that cooler's base simply rocking on top of CPU instead of making good contact:

Which is very counterproductive for true cooling power:
Without big size you can't have truly big surface area for dissipating heat to air.
Did you read the OP's? issue with cooler? Size....
